Embodiment 1

[0022] Test site: Embankment Test Station, Gaocheng County, Shijiazhuang

[0023] Experimental field: summer corn field with stubble sowing

[0024] Test time: July 18-24, 2011

[0025] Test method: use a basin trap for the test, use a green hard recycled plastic basin with a diameter of about 25 cm, drill two drainage holes symmetrically at 1 cm below the edge of the basin; pass a thin iron wire through the hole through the rubber plug of the lure core Fix the rubber stopper in the middle of the basin; fill the basin with clean water to the bottom of the drain hole, add a spoonful of washing powder (concentration of about 0.3%) or a small amount of washing liquid, and stir well; adjust the height of the wire so that the bottom of the lure core is high The water surface is 0.5~1.0 cm; the height of the trap installation is 20cm higher than the top of the corn plant, and the traps are arranged at an interval of 20m in the field.

[0062] Experimental field: summer corn field with stubble sowing

[0063] Test time: August 1st - September 7th, 2011

[0064] Test method is the same as embodiment 1

[0065] Test treatment:

[0066] A: 95% by weight of active component A and 5% by weight of synergist B, wherein synergist B is 2, 6-di-tert-butyl-p-cresol;

[0067] B: 95% by weight of active component A and 5% by weight of synergist B, wherein synergist B is a mixture of 2,6-di-tert-butyl p-cresol and citric acid, and the weight ratio of the two is 10:1;

[0068] C: blank control

[0069] In each treatment, the total weight of the active components cis-7-dodecene acetate and cis-9-tetradecene acetate was 1 mg, and each treatment was repeated 3 times.

[0070] results and analysis

[0071] It can be seen from Table 3 that the addition of citric acid can significantly improve the moth-attracting effect of the sex attractant and pro...

Abstract

The invention relates to an insect sex attractant, in particular to a highly-efficient sex attractant for Athetis lepigone. The highly-efficient sex attractant for the Athetis lepigone comprises an active ingredient A and a synergistic agent B, wherein the active component A consists of cis-7-dodecenyl acetate and cis-9-tetradecenyl acetate in a weight ratio of (5:1)-(1:5); the synergistic agent B is 2,6-di-tert-butyl-p-cresol; and in a more preferable embodiment, besides the 2,6-di-tert-butyl-p-cresol, the synergistic agent also comprises citric acid. Compared with the reported sex attractant for the Athetis lepigone, the Athetis lepigone attracting effect of the highly-efficient sex attractant for the Athetis lepigone is significantly enhanced by several times.

Description

technical field [0001] The invention relates to an insect sex attractant, in particular to a high-efficiency sex attractant for the spodoptera moth. Background technique [0002] Two o'clock moth[ Athetis lepigone (M?schler, 1860)] is a new agricultural pest in my country's summer corn production areas. [0003] According to relevant records, in July 2005, it was first discovered in Shijiazhuang, Hebei Province in China that the two-spot moth damages summer corn seedlings, bores the base of the stem, causes the seedlings to wilt and die, or bites off the corn roots, leading to lodging, causing Serious lack of seedlings and monopoly, this is the first report in China. According to reports, in 2010, Noctuid moths commonly occurred in the central and southern summer corn areas of Hebei Province, and broke out in Hebei, Henan, Shandong, Shanxi, Anhui, Jiangsu and other provinces in 2011, with an area of ​​more than 30 million mu, accounting for 100% of the summer corn area. 2...
